1. Use a media player. Most media players, such as Windows Media Player or iTunes, allow you to add album art to your songs. To do this, simply right-click on the song in your library and select "Properties" or "Get Info." Then, click on the "Artwork" tab and select the image you want to use.
2. Use an external program. There are also several programs that you can use to add album art to your songs. Some popular programs include Mp3tag and TagScanner. Simply install the program of your choice and then follow the instructions to add album art to your songs.
Here are some additional tips for adding pictures to your downloaded songs:
* Make sure the image you use is the same size as the album art that is displayed in your media player.
* If the image is not the same size, you may need to crop or resize it before adding it to your songs.
* If you are adding album art to a large number of songs, you may want to use a batch processing program to automate the process.
* Adding pictures to your downloaded songs can help you to organize your music library and make it more visually appealing.
